The only lead here that says what it carries.

Thirty amps

At 1500 V DC, from −40 °C to +90 °C. Three figures on one line. Across six solar cables and five extension leads in this family, this is the only listing to publish a current rating at all.

Cable is sold in square millimetres and bought to carry amps, and every other listing leaves that conversion to the reader.

The materials

Oxygen-free tinned copper, cross-linked polyolefin insulation. Both named, both correct for the application.

The pair

Two leads, both poles. Available in 4 mm² or 6 mm² so it can match an existing run.

The lines still left blank

An ingress rating, which the connectors have and the listing does not state. And the voltage drop, which no lead in this family publishes.

Availability

German Amazon store quoted about 8 € when this page was compiled.

American, British, French, Italian and Spanish Amazon stores returned nothing at all, so the buy button there runs a search instead of landing on an empty page.

These figures are what Keepa reported on the day this page was last updated. Availability and pricing move without notice.

Prices quoted in this text were read on 16 September 2026. The live price is at the top of the page.
